Before America votes, what can Biden and Trump’s responses to past crises — both personal and political — tell us about how they might lead the United States through a time of national turbulence? 

In this episode, Michael Kirk, veteran FRONTLINE filmmaker and director of The Choice 2020: Trump vs. Biden, reflects on how the candidates have confronted challenges and setbacks throughout their lives and careers, and how the stakes in this election cycle feel especially high. Having conducted nearly 50 new interviews for this film, his fifth installment of The Choice, Kirk says: "Most people can't remember a starker choice. I really think everybody thinks this is the election of the century."

The Choice 2020: Trump vs. Biden premieres on PBS and online Tuesday, Sept. 22.
